Ancillary Products to Improve Molding Process Efficiency

Mold Cleaners for Polyurethane Molding

Chem-Trend® Mold Cleaners are designed to address the needs of virtually any type of polyurethane manufacturing process. They are formulated to powerfully but safely attack resinous mold build-up. These highly engineered cleaners are designed to remove waxes, silicones, contaminants, polyurethane and polyurea residues from both pre-production mold preparation and on-line molding applications. Mold cleaners can be supplied as a liquid or a gel, depending on your process. In fact, by using our mold cleaners, some customers have eliminated the need for expensive dry ice blasting.

Mold Sealers and Preparation Pastes for Polyurethane Molding

Chem-Trend® Sealers and Preparation Pastes provide a durable barrier to prevent mechanical and chemical bonding during molding operations. These products are an excellent way to prepare new tooling and to provide an effective base for enhancing release from difficult mold surfaces. Our mold sealers and pastes have been formulated to work most efficiently in combination with Chem-Trend® release agents in pre-production or on-line production touch-up applications.

Low Pressure Mixing Head Flush Solutions for Polyurethane Molding

Chem-Trend® Head Flush Solutions can be used to effectively clean out the mixing head chamber in certain low pressure processing applications. Our head flush solutions are easy-to-handle and are the most powerful resin removers available for polyurethane systems. Long down time to allow for cleaning between successive shots can be eliminated with these highly efficient, fast drying solvents. For customers using different colored polyurethane systems through the same mix head, our head flushing products can help minimize scrap between color changes.

Anti-Squeak/Noise Reduction (NRT) Products for Polyurethane Molding

Our anti-squeak products are water-based. They’re applied to eliminate squeak wherever rubbing could cause noises that might be heard by the end user.

All Chem-Trend products for polyurethane molding are developed to work together in a total system approach, leveraging individual product strengths to provide for significant improvements in your production performance.

Common Questions:

What process aids are available to assist with difficult areas or damaged tooling?

Paste waxes provide an excellent barrier for starting up on clean molds. These materials provide protection in scratched, cold, or high pressure areas, and provide a durable layer that will help to minimize complications due to defects on the metal surface. Mold sealers improve the performance of the release agent by creating an optimal surface to release the parts from. Sealers are applied only to freshly cleaned tools but the benefit lasts throughout the production and cleaning cycle.
